There is a denial of service vulnerability in Huawei products. A module cannot deal with specific messages due to validating inputs insufficiently. Attackers can exploit this vulnerability by sending specific messages to affected module. This can cause denial of service. Affected product versions include: S12700 V200R013C00SPC500, V200R019C00SPC500; S5700 V200R013C00SPC500, V200R019C00SPC500; S6700 V200R013C00SPC500, V200R019C00SPC500; S7700 V200R013C00SPC500, V200R019C00SPC500.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 7.5, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts and availability (service disruption) for affected systems. Impacting 8 products from huawei, from huawei, from huawei and 5 others, organizations running these solutions should prioritize assessment and patching.
Reported in 2021, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For huawei's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
